Telex ANR 500
 

Almost new and I have everything they came with. Selling because they're not needed on my aircraft. Private message a reasonable offer to me, and they're yours. I'll ship at my expense. If you don't like them, ship 'em back.http://www.telexwireless.com/UserFil...aft/arn500.jpg
I suggest reading specs and info. on them at the telex website, please forgive the external link: Telex - Aviation Headsets
They retail for between $400 and $+500
